Subject: SCSI: remove fake "address-of" expression
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=e6da54d84f9286edbe4c92ff5023ff481ce2a5c9;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

SCSI: remove fake "address-of" expression

Fake "address-of" expressions that evaluate to NULL generally confuse
readers and can provoke compiler warnings.  This patch (as1411) removes
one such fake expression, using an "#ifdef" in its place.
